#Historical concealment and distortion in the Cold War During the cold war, there were indeed many historical events that were deliberately concealed or distorted, and these actions seriously affected the accurate understanding of international relations. Some of the main examples include： 1. ** The inside story of the Cuban missile crisis**-The public did not know until many years later that the deployment of missiles by the United States in Turkey was part of the reason for the deployment of missiles by the Soviet Union in Cuba, and the agreement reached by the two sides through secret channels to remove Turkish missiles. 2. ** Intelligence operations and regime change**-The secret operations of the United States and the Soviet Union in third world countries, such as the regime changes that the United States participated in in Iran (1953), Guatemala (1954), and Chile (1973). 3. **The true scale of the military conflict**-Secret bombing operations in the Vietnam War, the military involvement of Cambodia and Laos was deliberately watered down 4. ** Satellite surveillance and the Arms race**-Both parties' assessments of each other's military capabilities are often deliberately exaggerated or underestimated to support their respective political goals This information manipulation has affected international relations in several ways： -Created an atmosphere of mutual distrust between the two sides -Affected the public's understanding of the nature of the conflict -Provides a reasonable excuse for the arms race -Hindered a potential diplomatic solution With the decryption of archives and the research of historians, many of these events are now being re-evaluated, providing us with a more comprehensive perspective on the history of the Cold War.
